Thanks all! I appreciate your replies. I am slowly moving up the learning curve. Until the late 1990s, I have a purchased raw coins from local coin shops. Then, when I began online purchases, I focused on slabbed coins. It seemed like a big deal back then to collect proof 70s. I remember there were online businesses that focused almost exclusively on selling modern proof 70s. Being new to buying slabbed coins back then, I thought buying the highest grade was the way to go. With proof 70s selling at extraordinarily high prices, I think what happened was that many proof coins were being submitted to TPGs in hopes of getting one returned as a proof 70. Eventually, the population of these coins increased and their values decreased. I am sure that the more experienced collects here are already aware of this. I still have many of these coins that are now worthless. Back then, I bought a PCGS PR70DCAM 1983 S Kennedy half dollar for $450. I just checked the PCGS price guide and it is valued at $70. Unfortunately, I learned the hard way. TheMont hit the nail on the head. Last winter I bought a beautiful PCGS AU 58 CAC 1932-S Washington quarter for $300 that I wouldn't trade for one graded MS 65 that's selling for more than ten times that amount. I think that I enjoyed buying raw circulated Indian Head pennies as a kid more than breaking the bank trying to buy top graded slabbed coins. As a kid, I focused more on the coin. Later on, I seemed more focused on the plastic slab. In conclusion, I realize that I have placed too much emphasis on a single (grading) number when there are so many other factors to consider. For mint state coins, what do these numbers actually represent? It doesn't seem to take into account ugly toning with black spots. It doesn't seem to take into account how well a coin is struck. So, if I decide to buy a proof silver Kruggerand, I will take your advice and focus on the coin and not on the slab.
